CK Vul: a smorgasbord of hydrocarbons rules out a 1670 nova (and much else besides)
A. Evans, R. D. Gehrz, C. E. Woodward +5
We present observations of CK Vul obtained with the Spitzer Space Telescope. The infrared spectrum reveals a warm dust continuum with nebular, molecular hydrogen and HCN lines supe…
Probing the Local Bubble with Diffuse Interstellar Bands. I. Project overview and Southern hemisphere survey
Mandy Bailey, Jacco Th. van Loon, Amin Farhang +4
We have conducted a high signal-to-noise spectroscopic survey of 670 nearby early-type stars, to map Diffuse Interstellar Band (DIB) absorption in and around the Local Bubble. The…
Mapping atomic and diffuse interstellar band absorption across the Magellanic Clouds and the Milky Way
Mandy Bailey, Jacco Th. van Loon, Peter J. Sarre +1
Diffuse interstellar bands (DIBs) trace warm neutral and weakly-ionized diffuse interstellar medium (ISM). Here we present a dedicated, high signal-to-noise spectroscopic study of…
Theoretical study of deuteronated PAHs as carriers for IR emission features in the ISM
Mridusmita Buragohain, Amit Pathak, Peter Sarre +2
This work proposes deuteronated PAH (DPAH+ ) molecules as a potential carrier of the 4.4 and 4.65 μm mid infrared emission bands that have been observationally detected towards the…
The 6614 diffuse interstellar absorption band: evidence for internal excitation of the carrier
Charlotte C. M. Marshall, Jacek Krełowski, Peter J. Sarre
An analysis of absorption profiles of the 6614 diffuse interstellar band recorded along the lines-of-sight towards HD 179406 (20 Aql) and HD 147889 is described. The difference…
The 11.2 m emission of PAHs in astrophysical objects
A. Candian, P. J. Sarre
The 11.2 m emission band belongs to the family of the `Unidentified' Infrared (UIR) emission bands seen in many astronomical environments. In this work we present a theoretical…
